  • Answer:
  • add all the equation for example the first question in there would be like

(note - an equation contains an is equal to sign [=] and if a problem does not have an is equal to sign then it becomes an expression)

  • Step-by-step explanation:

  • 2n°, 55°, 49°

just add all of them making an equation like

2n° + 55° + 49° = 180° (angle sum property)

2n° + 104 = 108°

2n° = 108° - 104

i.e., 2n° = 76°

n = 76/2 therefore,

n = 38

Please help me answer this.
Mariulka [41]

Answer:

(a) 3

Step-by-step explanation:

Calculate the slope m of the line given using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)

m = \frac{2-3}{3-0} = - \frac{1}{3}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{1}{3} } = 3 → (a)

Ken read 30 pages of a book on monday and 1/8 of the book on tuesday, he completed the remaining 1/4od the book on wednesday.how
dlinn [17]
Let the total amount of pages be t
t=30+1/8t+2/8t
now simplify
t=30+3/8t
5/8t=30
divide 30 by 5
1/8=6
now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
